Cannot read windows disk when booting from usb key


Hi,

Using rufus I created a bootable usb key with an iso image from linux Ubuntu 14.04.
I booted with the key with success but the Windows hard disk is not accesible.
The disk icon appears in the laucher but when I click on it Nothing happens.
My secondary disk with only data is accessible and my dvd as well.
Any help is appreciated.

Thank you

Bruno

Possibly you are missing the appropriate filesystem kernel modules.

fat/fuse, and the ntfs-ng tools.

First off, I'd recommend Ubuntu 16.04 instead of 14.04. Maybe you just mis-typed? Newer is usually better unless you have some limitation that needs an older version.

If you're using Windows 8, 8.1, or 10, it's possible that you're not able to access the Windows partition because it is in hibernation, although I think an error is usually presented. Windows can be left in hibernation if you choose Shutdown in Windows before booting your USB key. To rule this out, run Windows again, insert your Ubuntu USB key, and then choose Restart instead of Shutdown.

If this turns out to be the problem and you want a more permanent solution, check this out.

Let me give some precisions:

My primary hard disk contains 3 partitions, the Windows loader 500mb partition, the Windows 10 partition and an ext4 partition with linux Ubuntu 14.04 on it.

The loader partition and the Ubuntu parttion are accessible but only the Windows 10 partition is not accessible.

I also tryed to boot from my Ubuntu usb key on an XP computer and the system partition is accessible

It would be great if you responded concerning advice that's already been given to you. I have a feeling your answer is in post #2

Try to determine which file system your MS Windows installation is using, then check that you have the necessary supporting file system software on your Ubuntu system.

This command from Linux should show you.
Code:
sudo fdisk -l /dev/sda

Thanks for the quick and numerous replys,

Here is the results of fdisk -l

I think sda2 is my Windows partition, is it the right file system for Ubuntu 14.04?
(I am not knowledgable enough in linux for knowing)

Have you tried mounting the partition via terminal?

Yet your fdisk output shows three windows partitions, a Linux partition and a swap partition. The windows partition are probably a boot partition, a system partition and the Recovery partition. You also have an Extended partition with two logical partitions including the Ubuntu and swap. You mention a 'primary hard disk' but the fdisk output only shows one hard drive?

I'm not sure what you mean by that. It's the right filesystem for windows.

I'm not sure why you are trying to boot the iso when you have Ubuntu installed. Can you not boot the installed Ubuntu? If you don't have the correct software mentioned in post 2, you could easily install it on Ubuntu. Maybe if you explained why you are trying to do this and what you want to accomplish someone would have a suggestion.

Downlaoding and running the bootinfoscript or boot repair and posting the output would give more details. Boot repair link is below and if you use it, select the option to Create BootInfo Summary and post a link here.

Windows 8 10 default to never actually shutting down, they go into hibernation so upon boot up they come up faster. Because my Windows 10 is on a SSD, to get the best lifespan from a SSD you should set the OS to minimize the amount of writes to the drive. So, in settings you can set it to actually shutdown when you choose to shut it down. Since I have newer SSD through PCIe bus, that did not slow down Windows ability to come up fast by much, maybe 2 or 3 seconds longer.

I just tried mounting my Windows 10 partition and needed to enter root password and I have access.

Also, Windows can be set to encrypt drives. If it is encrypted, this can pose a problem when trying to auto mount.

Also, in Windows 10 settings, you can set it to have default save directories in the data partition, again, this reduces the amount of writes to the SSD in my case. One click of the mouse and your user name appears in the data drive, in that folder are the other folders, such as: Documents, My Music, My Pictures, etc.

So, with one click of the mouse in Windows 10 settings, you won't need to mount the OS partition or drive.

I understand the confusion,

what i'm trying to do is create a
boot key so that I can recuperate data on systems that are corrupted with viruses and won't boot anymore.
I encountered a problem with a pc that wouldn't boot in Windows because it was heavily infected
and then
my friend booted with a linux key and the data was recuperable.

I just wanted to create a boot key to do the same as my friend.

So, from the posts it seems that my problem is a hibernated system, anyone could tell me how to shutdown out of hibernation?
I tryed shutting down holding the shift key but I don't know if my system is out of hibernation.

Thanks to all for your'e patience... I am Learning still.

In post #6 you said that you "restarted" your computer with the USB key. If in fact, you did restart, then hibernation is not your problem. Hibernation happens when you do a full "shutdown" from Windows 10.

If not careful, recovering files from virus-infected computer may bring the virus with it (although not really a danger to Linux). If this is your goal, you might Google for "bootable anti-virus usb" where there are many products to help Windows users with this trouble.

I just checked that I can access a Windows 10 disk from Linux (Opensuse 13.2). Before recent updates (to both Windows and Opensuse), such an attempt failed with *disk busy* or some such error message. Maybe your software needs updating. For the record, I am currently running Linux from a memory stick with legacy boot: Windows is protected boot.
